commit 4001e93682384f195628f5c2609b52332558c7c8
Author: Michael Meissner <meiss...@linux.ibm.com>
Date: Thu Nov 14 13:52:47 2024 -0500
Change TARGET_POPCNTB to TARGET_POWER5.
This patch changes TARGET_POPCNTB to TARGET_POWER5 and OPTION_MASK_POPCNTB
to
OPTION_MASK_POWER5. The -mpopcntb switch is not being changed, just the
name of
the macros used to determine if the PowerPC processor supports ISA 2.2
(Power5).
